The plate is fixed to the inner face of the demoun table rim andalthough the rim structure itself is no part of the present inventionthose features thereof which cooperate with the tool will be describedfor facility of disclosure of the utility of the tool. The plate 15, asclearly seen in Eigs. 3 and 4, is formed with an intermediateoff'setportion which is spaced from the inner surface of the rim 16 whilethe-plate is riveted or otherwise fixed thereto, and it is in thisparticular offset 'portion that the aperture 17 is formed. The

, a rture 17 in addition'to being substan- 'tlally oblong is formedintermediate its ends with arcuate enlargements 18, 18, corresponding inproportions. to the proportions of the neck or reduced portion 4 o post4, so that the said neck may revolve freely within the aperture 17 whenin register with said enlargements 18. Thus, in operation, the button 5may be readily introduced through the aperture 17 until the neck 4occupies the space formed by the aperture 17 and enlargements 18, andthen the post is revolved through ninet degrees so as to bring theprojecting en s of the button 5 into the position under-hanging theoffset portion of plate 15. At the same time the annular shoulder ofpost 4 above. the neck or reduced portion 4- overhangs the said plate,as clearly indicated in- Fig. 3, and the post is thus effectivelyanchored to the rim in a manner capable of easy detachment and readyapplication. As seen in Fig. 2, the lever 1' will be in the positionindicated in dotted lines across the rim when the tool is being appliedand will be in the position indicated in dotted lines parallel to therim when the'tool is anchored and ready for use, The removal of the st 4requires merely that the lever shall 'e swung from the latter to theformer position and the post lifted out of its engaging socket formedlate 15.

he rim 1c is cross-cut near the plate 15 separated. sufficiently toenter" the a ertures' 19 and thereupon the nut 14ft; threa ed back fordrawln-g the links 9 toward each other sufiiciently for causing-them'to. clasp the interposed rim.

This conditions therim either to receive or permit the removal of a tirehavinganon-extensible bead.

As a matter of facilit in operation, the lever 1 is preferably 0 set, asclearl seen BO in Figs. 6 and 11, so as to bring the .iandle part of thelever approximately in the plane of the edge of the rim. To increase theleverage and proportionally increase the ease of manipulation, thishandle part is. prefer- 8 5 rim may be restored to its former conditionby swinging the lever 1 back to the sition indicated in Fig. 9, and Ifind that'in practice the tool constructed as described is veryeffective in forcing the end of the rim having the eyes 19 back into itslatch-engaging position, A very similar operating tool to the 7 abovedescribed is set forth and claimed in my co-pending application SerialNo; 135,071, filed December 4, 1916, but I find I that the-play allowedthe links in the struc ture shown in that application is not suffi--cient for enabling the tool to be applicable to a very large range ofsizesof rims; In' other words the tool as set forth and claimed inthe"said application is effective for a definite siae of rim or perhapsfor some variations in sizes, but is not well adapted for all sizes asis the tool herein set forth. "This is due to the fact largely that thelinks 9 as disclosed herein are allowed the widest possible range ofadjustment in every direction relative to their engagin Y andrestraining devices.

11 igs. 7, '8, 8 and 8", I, have shown a slightly modified embodimentwherein the fulcrum post 4 is provided with a button 5 and other artscorresponding with the post 4 with the exception that the button 5- isparti-globnlar on its under face as-indicated at 5". The rim l6 iscorrespond- 1215 ingly depressed to form a parti-spherical re-. cess forthe rece ion of the under 'face of the button 5. e other lparts in thismodidetail dewription. It is obvious that the ty es of rims.

, hat is claimed is 1. An operating tool for manipulatin a cross-cutdemountable rim comprising a ul crum post adapted to be rigidly anddetach; ably connected to the rim, a lever pivoted to said post, a shaftpivotally engaged by the lever and having elongated reduced bearings, alink pivotally'engaging each bearing and having an eye surrounding thebearing, the eye being formed with a double bevel for receiving the linkfree to rock on the bearing, and to have free lay thereon in alldirections, and means 0 engagement on thelinks adapted to engage theopposite end portion of the rim from that engaged by the post.

2. An operating tool for manipulating a. cross-cut demountable rimcomprising a fulcrum post having a button at one end of greater lengththan width and having a shouldered portion spaced from the button forenabling the button to be inserted in a slot through a portion of therim and't'o be rotated-beneath the material of the slot so that theterminals of the button will underhang such material while the shoulderoverhangs the material, and means engaging'the fulcrum post for shiftingone end of the rim relative to the other.

3. An 0 crating tool for manipulating a cross-cut d e mountable rimcomprising a ulcrum post having a button at one end of greater length.than width and having a shouldered portion spaced from the button forenabling the button to be inserted in a slot through a portion, of therim and to be rotated beneath the material of the slot so that theterminals of the button will underhang such material while the shoulderoverhangs thematerial, and means engaging the fulcrum post for shiftingone end of the rim relative to the other, the said button being formedwith a parti-globular face.

In testimony whereof I aflix my signature in presence of two witnesses.
